I soaked it with Lace Release, the 91% alcohol, then Autoglym and it was still stuck on there rock solid. I thought I was going to rip the poly when I finally was able to get a corer up and pull the pieces off. I'm not actually sure what tape it is. I bought it a year ago when I first started wearing but had such a bad reaction to all tapes that I never used it again until last week when I tried it with the scalp protector.
